Solve for x: |3x + 2| = 2

Question

anonymous · Answer

make two equations out of it, one positive and one negative.

anonymous · Answer

$$-3x+2=2$$

anonymous · Answer

$$3x+2=2$$

hiroromon · Answer

you are solving for x not getting rid of the x

anonymous · Answer

Thats how you solve...

anonymous · Answer

They are two separate equations smart one.

hiroromon · Answer

no you would get x on on side by subtracting the 2on the side with the x with the 2 on the other side

anonymous · Answer

Cause its absolute value so you must make two different equations and solve for x on both.

hiroromon · Answer

ok if you do it your way you would get 0 + 4 = 4

anonymous · Answer

No you wouldnt...I never did say to add them together? just said make two equations.

anonymous · Answer

why dont you go look up what absolute value is :)

hiroromon · Answer

>.>

hiroromon · Answer

anyway this is what you would do

hiroromon · Answer

the product of an abosulte value can be either negative or positive

anonymous · Answer

Right...

hiroromon · Answer

therefore in order to find the value of x you would normally solve it by doing this

anonymous · Answer

My way would be...$$-3x+2=2                                      -3x=0$$

anonymous · Answer

The problem is not answerable.

hiroromon · Answer

3x+2 = 2
    -2    -2 
= the answer below
3x=0
--  -- = undefined
3     3

hiroromon · Answer

and since it's absolute value you change the answer to a negative like so
3x+2 =-2

hiroromon · Answer

and you do the same thing

anonymous · Answer

But thats not how you do it in the future, for this problem that works but usually you must make two separate equations.

anonymous · Answer

Actually your wrong the answer is 0 and -3/4

anonymous · Answer

*-4/3
